Low-dielectric-constant glass fibers having a glass composition comprising, by weight %, 50 to 60% of SiO2, 10 to 18% of Al2O3, 14% to less than 20% of B2O3, 1% to less than 6% of MgO, 2 to 5% of CaO, 0.5 to 5% of TiO2, 0 to 0.3% of Li2O, 0 to 0.3% of Na2O, 0 to 0.5% of K2O and 0 to 2% of F2, the content of MgO+CaO being 4 to 11% and the content of Li2O+Na2O+K2O being 0 to 0.6%. The glass fiber has a low dielectric constant and a low dielectric tangent, is excellent in productivity and workability and is also excellent in water resistance, and the glass fiber is suitable for reinforcing printed wiring boards for high-density circuits.

An ice dispensing chute mechanism is characterized by an ice chute adapted for attachment at an upper ice inlet end to an ice retaining bin at an ice outlet from the bin. An actuating arm is pivotally mounted on the ice chute and has a lower end for being contacted and moved by a receptacle into which ice is to be dispensed from a lower ice discharge end of the chute and an upper end for contacting and moving a linkage mechanism upon rotation of the actuating arm by the receptacle. The linkage mechanism is pivotally mounted on the ice chute and is coupled to an ice gate that is linearly moved by the linkage mechanism between open and closed positions that establish and interrupt communication between the upper inlet to the chute and the ice outlet opening from the bin. Movement of the linkage mechanism by the actuating arm operates the linkage mechanism to translate the rotational movement of the actuating arm into linear movement of the ice gate between its open and closed positions to dispense ice and to cease dispensing ice into the receptacle. The ice chute consists of two halves that snap together in a releasable manner to permit easy disassembly of the ice chute for cleaning, repair or replacement of parts. The upper inlet to the ice chute is configured to impart to ice particles a trajectory through the chute that guides the ice particles into the receptacle while preventing the vast majority of the ice particles from contacting interior surfaces of the chute.

A bottle carrier / cooler is provided for easy, convenient transportation, cooling and storage of a single conventional plastic beverage bottle. The bottle carrier / cooler is configured to substantially contain one standard bottle while exposing the bottle neck and bottle cap. The body of the bottle carrier / cooler is of a diameter sufficient to maintain ice, water or other refrigerants so the bottled beverage will remain at a desirable low temperature. The beverage which may be a soft drink, can be poured from the bottle without removing the bottle from the carrier / cooler. A seal connected to the carrier / cooler lid prevents leakage of the refrigerant while the beverage is poured and in conjunction with projections along the bottom of the carrier / cooler stabilize the bottle longitudinally. In the preferred embodiment of the invention a lid having a pour spout and finger tabs is provided. A cover or sleeve is utilized to surround the bottle before placement within the carrier / cooler to maintain the refrigerant placed therein free from dirt and debris. The pour spout provides access to the potable water contained therein as the ice melts.

A process in which a polycrystalline silicon ingot improved in life time characteristics, which are correlated with the conversion efficiency of solar wafers, is inexpensively produced by the ordinary-pressure hydrogen-atmosphere melt method. In the process, the generation of oxygen and impurities in the silicon melt is inhibited and light-element impurities are removed through reaction or crystallization. Fine crystal grains can be grown at a high rate, and a high-purity polycrystalline silicon ingot having a crystal structure reduced in crystal defect can be grown. A silicon raw material is melted in an atmosphere of 100% hydrogen at ordinary pressure or an elevated pressure to prepare a silicon melt and simultaneously dissolve hydrogen in the silicon melt. The silicon melt containing hydrogen dissolved therein is solidified. Thereafter, the solid is held at a high temperature around the solidification temperature to grow silicon crystal grains in the solid phase and thereby obtain a polycrystalline silicon ingot.
